The farm implement of this invention is movable across ground along a direction of travel for tillage. The farm implement includes at least a frame and a multi-disc unit. The multi-disc unit includes pluralities of first and second discs, each having a ground-engaging outer periphery defining a plane angled acutely relative to the direction of travel. The first discs are angled to an opposite side of the direction of travel than the second discs. Positioned between the plurality of first discs and the plurality of second discs is a first flow controller assembly, preferably a coulter assembly. Positioned behind the plurality of second discs is a second flow controller assembly, preferably a coulter assembly.
